17
Q

what are areas that must be labeled as a double hearing protection area

A

equal to 96dBA or great or 165 dBP or greater must be labeled as a noise hazardous area and require the use of double hearing protection

18
Q

Hearing testing and medical surveillance periodicities:

A

reference hearing test
monitor hearing test
termination hearing test

19
Q

reference baseline audiogram form

A

DD-2215, the baseline at MEPS DOES NOT count

20
Q

Monitoring audiogram for HCP form number

A

DD 2216

21
Q

no protection required for noise levels less than or equal to how many dBA?

A

84

22
Q

single hearing protection and placement in HCP noise levels

A

85 dBA or greater but less that 96 dBA.

23
Q

double hearing protection and placement in HCP noise levels:

A

96 dBA

24
Q

Who takes measurements to measure levels of noise at different sites?

A

industrial hygienist and or occupational audiologists

25
Q

Industrial Hygienist or Occupational Audiologist measure noise levels to determine potential hazard and how sound level?

A 
85 dB (continuous or intermittent) or 140 dB peak sound level 
should be analyzed to determine hazard.  
Resurvey 30 days after any modifications or changes that could impact
26
Q

Record of noise measurements shall be kept the measuring activity for how long?

A

50 years

27
Q

What is a Significant Threshold Shift (STS)

A

a change in hearing threshold relative to the current reference audiogram for 10dB or more at 2000, 3000, and 4000 Hz in either ear.

(May be either positive or negative)

28
Q

STS Identification procedures if the STS is negative

A

audiogram may be in error. retest the same day. if still showed improved hearing, assume the reference audiogram is in error.

29
Q

STS identification procedures if the STS is positive

A

retest after 14 hour noise free environment
supervisor should be notified.
if retest does not indicate STS, return to annual monitoring.

30
Q

if retest of STS shows positive, and frequencies below 3000 hz involved

A

screen for med conditions (otoscopy and tympanometry)

record on SF600

31
Q

if findings through otoscopy and tympanometry are abnormal what must be done

A

health care evaluation must be obtained and individual followed until cleared medically.

32
Q

if findings through otoscopy and tympanometry are normal what must be done

A

perform a second retest

33
Q

if the second retest does not indicate a STS:

A

return to annual monitoring

34
Q

if second retest shows STS:

A

hearing protection is evaluated
results are forwarded to audiologist/physicians for review and disposition
results usually used to reestablish baseline

35
Q

within how many days should the supervisors be notified in writing of positive STS?

A

21 days

36
Q

OSH office makes entry in what form for a Permanent Threshold Shift?

A

OPNAV 5102/7 (Log of Navy Injuries and Occupational Illnesses)

37
Q

within how many days will the worker be notified of a Permanent Threshold Shift?

A

21 days. signature on dd2216 will suffice as an appropriate notice

38
Q

what is the purpose of the “noise free audiogram”

A

exclusion period from noise, “auditory rest”

14 hours is usually sufficient to allow a temporary STS to return to pre exposure levels

39
Q

Noise Abatement Strategies: Engineering controls

A

primary means of protection
acoustical enclosures
engineering designs to eliminate or reduce noise levels

40
Q

Noise Abatement Strategies: administrative controls

A

secondary means.

limiting times of exposure

41
Q

Noise Abatement Strategies: Substitution

A

substitution of less noise operations

42
Q

types of personal hearing protective devices

A 
ear plugs
disposable 
single flange 
triple flange 
straightaway muffs 
circumaural muffs
43
Q

training requirements for personnel enrolled in the NHCP:

A

trained PRIOR to working in hazardous areas

training shall be conducted on an annual basis
